Description

A whole hand-held grinding stone, also known as a mano in Southern California archaeology. This bifacial stone is used with one hand for grinding and was shaped in construction. It is oval in shape. The stone material is a granitic with muscovite and gold (weathered biotite) mica. It is coarse grained.

This grinding or milling stone's ventral side is slightly pecked, polished and stained. Its dorsal side is pecked and polished. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. The stone appears to be pecked on the grinding surfaces; pecking increases the grinding surface for greater traction.
